Public Trust fee-protection submissions

Record each learner's fee-protection submission and move it through pending, submitted and cleared.

1. Under Administration → Modules, enable Public Trust Fee Protection.
2. Open Administration → More → Public Trust. Under New submission, enter the learner's Student ID, the NZD amount and a unique reference, then Create. The row shows pending. An unknown Student ID is refused with Student not found.
3. Select Mark submitted, then later Mark cleared. Each state survives a reload.
